Five years ago the world lost one of its most prolific insurance scholars, Dr. Robert I. Mehr. His death in 1988 signalled the passing of not only a gifted writer and researcher, but also a pioneering teacher, mentor, and friend. The essays compiled within this volume are intended as an appropriate tribute to this occasionally outrageous individual who touched the lives of so many within the insurance community. Bob Mehr was a teacher who expected and demanded nothing less than perfect scholarship and flawless, efficient writing. Among alumni of the University of lllinois insurance doctoral program, stories still abound of late night and early morning sessions in which students and professor painstakingly debated precise words and phrases for dissertations, journal articles, and textbooks. Bob's respect for language was both immense and contagious, if at times more than a little compulsive. He joked that he could not read letters or novels without pencil in hand for editing. Bob's respect for his doctoral students was equally evident. The confidence he displayed in his students' abilities was sometimes startling, but "competence assumed" often begot "competence in fact." The accomplishments and records amassed by the many who studied with Bob Mehr are impressive and ongoing. On the dedication page in his final textbook, Fundamentals of Insurance, Bob spoke of his affection for those he called his "academic progeny" and wished them happiness as they build their own academic families.

Economic and financial research on insurance markets has undergone dramatic growth since its infancy in the early 1960s. Our main objective in compiling this volume was to achieve a wider dissemination of key papers in this literature. Their significance is highlighted in the introduction, which surveys major areas in insurance economics. While it was not possible to provide comprehensive coverage of insurance economics in this book, these readings provide an essential foundation to those who desire to conduct research and teach in the field. In particular, we hope that this compilation and our introduction will be useful to graduate students and to researchers in economics, finance, and insurance. Our criteria for selecting articles included significance, representativeness, pedagogical value, and our desire to include theoretical and empirical work. While the focus of the applied papers is on property-liability insurance, they illustrate issues, concepts, and methods that are applicable in many areas of insurance. The S. S. Huebner Foundation for Insurance Education at the University of Pennsylvania's Wharton School made this book possible by financing publication costs. We are grateful for this assistance and to J. David Cummins, Executive Director of the Foundation, for his efforts and helpful advice on the contents. We also wish to thank all of the authors and editors who provided permission to reprint articles and our respective institutions for technical and financial support.

Property-liability insurance rates for most lines of business are regulated in about one-half of the states. In most cases, this me ans that rates must be filed with the state insurance commissioner and approved prior to use. The remainder of the states have various forms of competitive rating laws. These either require that rates be filed prior to use but need not be approved or that rates need not be filed at all. State rating laws are summarized in Rand Corporation (1985). The predominant form of insurance rate regulation, prior approval, began in the late 1940s following the V. S. Supreme Court decision in United States vs. South-Eastern Underwriters Association, 322 V. S. 533 (1944). This was an anti trust case involving one of four regional associa tions of insurance companies, which constituted an insurance cartel. The case struck down an earlier decision, Paul vs. Virginia, 8 Wall 168 (1869), holding that the business of insurance was not interstate commerce and hence that state regulation of insurance did not violate the commerce clause of the V. S. Constitution. Following South-Eastern Underwriters, the Vnited States Congress passed the McCarran-Ferguson Act, which held that continued state regulation and taxation of insurance was in the public interest. The act also held that the federal antitrust laws would not apply to insurance to the extent that the business was adequately regulated by state law. (See V. S. Department of Justice 1977."

In the 1980s and early 1990s, America's system of workers' compensation insurance was in trouble. As medical costs grew and benefits and compensable injuries expanded, costs of this insurance skyrocketed. In response, the states imposed price controls, but those controls caused unforeseen - and negative - consequences. The authors define the problems, trace the regulatory responses, and analyze the effects of rate regulation. Their study illuminates how rate regulation set up to control the cost of workers' compensation insurance reduced incentives for safety and cost control and subsidized high-risk activities and firms at the expense of others.
